Automatic speed cameras are catching out speeding boaties in marinas across Marlborough.
Hi tech cameras in Picton, Waikawa and Havelock Marinas are recording every vessel as it arrives and leaves.
Around ten people have been slapped with $200 infringement notices since the cameras were installed.
Acting Harbourmaster Jan Eveleens revealed the cameras have been calibrated to a high standard, like those used by police officers.
He says the Marlborough District Council funded cameras came after an idea to install signs like those that flash up speeds for motorists.
“I thought we should have them in the marinas, but they were not accurate enough.
“It’s been a bit of an experiment as they [the new cameras] were picking up waves and seabirds but they’re much better now, very accurate.”
The camera at Havelock was installed last winter while the Picton and Waikawa cameras were put up in December.
They record every vessels’ speed as they arrive and leave in the marina.
Boats going above the limit are instantly recorded and an alert goes to the Harbour Master.
Infringement notices are sent to boat owners by the council for breaking local bylaws.
Jan says people flouting the 8-knot speed limit as they arrive at Havelock Marina and the 5-knot limit in place at Picton and Waikawa will face fines.
“There have been some serial offenders but what we are seeing is that once word gets out is that people are slowing down.
“We had one boat coming into Havelock that drove straight into one of the beacons and the boatie hurt himself.
“People can hurt themselves if they are going too fast.”
The Harbourmaster will also monitor speed limits on the lower Wairau River from the State Highway 1 Bridge to below the Blenheim Rowing Club.
Jan says there have been reports of jet skiers on this stretch of the river going too fast.
The maximum speed in this section of the river is 5 knots.
“We want people to slow down and be safe,” he says.
